In conventional systems, data storage is distributed among individual servers, but storage networking technology such as the SAN (storage area network) and storage virtualization technology enable storage to be virtually consolidated on multiple storage devices in a storage network (virtual consolidation of devices). In this way, a corporate IT system administrator sees fewer storage devices to be managed, which can reduce the cost of managing storage equipment. Storage virtualization technology can be classified into four schemes according to the form of implementation. Hitachi has introduced a new version of enterprise storage that adopts highperformance, high-availability storage-based virtualization technology with proven functions from the existing product series. Storage consolidation can be expected to expand from virtual consolidation of devices within a single site to "wide area device consolidation" that can uniformly manage devices across multiple sites. In addition to storage system technology, Hitachi plans to continue its R&D (research and development) efforts in tiered storage management that manages consolidated devices according to their individual characteristics.
